24/08/12

Brazil's biomethane market continues to struggle to find ways to price its green attribute. Argus spoke to Gustavo Soares, a biomethane specialist and collaborator at market-focused research and opinion publishing site Ensaio Energetico about possible solutions, including a regulated carbon market. Edited highlights follow.

What is the biggest challenge to price biomethane's green attribute?

The biggest challenge is the lack of a regulated carbon market. If there were a carbon market, we would have companies with reduction commitments. It would be easy to calculate their demand for decarbonization and, consequently, for renewables or energy efficiency.

This would make pricing the green attribute much easier. We would move in a direction closer to the European market, where there is a reference price.

Can voluntary certificates, such as Gas-Rec, be a viable solution for this pricing?

[With voluntary certificates] it is up to the company to define its mandate and, if any cyclical or structural conditions change, they can simply review their commitment. Now, the certification helps in a certain way. The Gas-Rec is a traceability certificate that can meet some of the company's objectives.

Customers' willingness to pay more or less for a green attribute will depend on a series of factors, such as the company's own profile. A publicly traded company must have a lot of transparency, it has creditors who are concerned about decarbonization. An exporting company is possibly serving more demanding markets regarding environmental issues, for example.

In addition to creating a regulated carbon market, what other types of public policies could support Brazil's biomethane market development ?

There are many possibilities. A carbon tax [where consumers would be taxed for carbon emissions, instead of having decarbonization targets] would be one possibility. Tax exemptions for biomethane are another path. Taxes on LPG and diesel are often heavy. If there is an exemption or a large tax differentiation for biomethane, it creates a competitive advantage. The government can create a target obligation for public entities to consume biomethane.

Regarding infrastructure, the creation of incentives for connecting plants in distribution and to inject biomethane into transportation.

We must think about a set of policies. When we think about the development of biomethane, it will not be a policy that saves us, but a set of policies that will boost this industry.

ADB to fund Indonesia $92.6mn for geothermal expansion

Singapore, 15 January (Argus) — The Asian Development Bank (ADB) has signed a $92.6mn financing agreement with geothermal power producer Supreme Energy Muara Laboh (SEML) to develop Indonesia's geothermal power capabilities. The funds will go toward the expansion of a geothermal facility at Muara Laboh in West Sumatra, and the construction, operation and maintenance of a new 83MW geothermal power plant, the ADB announced on 14 January. The support will "help Indonesia to meet its clean energy targets and deliver affordable electricity," said the ADB's country director for Indonesia, Jiro Tominaga. The project will also allow Indonesia to enhance its long-term energy security, while reducing greenhouse gas emissions. The finance package consists of $38.8mn from the bank's ordinary capital resources, a $38.8mn "B loan" from Sumitomo Mitsui Banking, and a $15mn concessional loan from the Australian Climate Finance Partnership (ACFP). Indonesia has the world's largest geothermal energy reserves, estimated at 23.1GW, said the ADB. But the country is still heavily reliant on fossil fuels for its energy needs, with coal accounting for 61.8pc of Indonesia's power mix in 2023, while renewables accounted for 19pc. Indonesia's president Prabowo Subianto announced in November that Indonesia intends to retire all coal-fired power plants by 2040, and the government subsequently clarified that it is instead aiming for a coal phase-down . But a phase-out could be possible if the country rapidly increases its share of renewables in the energy mix to 65pc, according to energy think-tank Ember. This would mean a renewable energy target higher than the government's current goal of 75GW by 2040.

New York to propose GHG market rules in 'coming months’

New York to propose GHG market rules in 'coming months’

Houston, 14 January (Argus) — Draft rules for New York's carbon market will be ready in the "coming months," governor Kathy Hochul (D) said today. Regulators from the Department of Environmental Conservation (DEC) and the New York State Energy Research and Development Authority (NYSERDA) "will take steps forward on" establishing a cap-and-invest program and propose new emissions reporting requirements for sources while also creating "a robust investment planning process," Hochul said during her state of the state message. But the governor did not provide a timeline for the process beyond saying the agency's work do this work "over the coming months." Hochul's remarks come after regulators in September delayed plans to begin implementing New York's cap-and-invest program (NYCI) to 2026. At the time, DEC deputy commissioner Jon Binder said that draft regulations would be released "in the next few months." DEC, NYSERDA and Hochul's office each did not respond to requests for comment. Some environmental groups applauded Hochul's remarks, while also expressing concern about the state's next steps. Evergreen Action noted that the timeline for NYCI "appears uncertain" and called on lawmakers to "commit to this program in the 2025 budget." "For New York's economy, environment and legacy, we hope the governor commits to finalizing a cap-and-invest program this year," the group said. State law from 2019 requires New York to achieve a 40pc reduction in greenhouse gas (GHG) emissions from 1990 levels by 2030 and an 85pc reduction by 2050. A state advisory group in 2022 issued a scoping plan that recommended the creation of an economy-wide carbon market to help the state reach those goals.

California GHG rulemaking hits speedbump

California GHG rulemaking hits speedbump

Houston, 14 January (Argus) — The California Air Resources Board (CARB) cap-and-trade program rulemaking is likely to weather further delays, according to one of the agency's top officials. The agency's "immediate" responsibility is to work with covered entities impacted by the ongoing Los Angeles County wildfires across its programs, according to deputy executive officer Rajinder Sahota. This means that the rulemaking is not "imminent or in the next few weeks." In addition, the agency needs to move carefully given the federal administration change , along with the negative response to proposed updates to the state's Low Carbon Fuel Standard received last year. CARB continues to evaluate program changes, with a focus on affordability, ambition and compliance costs. "We want to take time to ensure we get out foundational facts about the program especially as the legislature takes up the post-2030 role of the program," Sahota said. The cap-and-trade rulemaking has been marked by a series of delays, as regulators initially in 2023 estimated it would finish last year. In December , CARB said it would delay the publication of draft amendments until early 2025. CARB began to prepare for the rulemaking nearly two years ago, floating the idea of moving the cap-and-trade program to a more-stringent 2030 greenhouse gas (GHG) reduction target of a 48pc, compared with 1990 levels, rather than the current 40pc mandate. The agency's 2022 Scoping Plan prompted the idea as it showed a need for increased program ambition for California to remain on track for its target of net-zero by 2045. In line with this increased ambition, CARB will need to remove at least 180mn metric tonnes (t) of allowances from the 2026-2030 auction and allocation annual budgets to start with, and up to 265mn t in total from the program budgets from 2026-2045, agency staff have said. Quebec, California's partner in the Western Climate Initiative (WCI) carbon market, previously delayed publishing its draft package from the originally planned September 2024 to the first quarter of this year, with implementation expected in the spring. While the regulation was nearly complete in late September, the Quebec Environmental Ministry decided to postpone, citing the need to wait for California. If California delays its work through the first quarter of the year, this will likely require Quebec to also push back its rulemaking. This will also shorten the runway for both market partners to formally implement changes by 2026. The news has punctured the bullish sentiment for market participants on a timely end to the rulemaking. California carbon allowances for December delivery initially traded as high as $35.25/t on the Intercontinental Exchange (ICE) ahead of the announcement. The contract traded as low as $33.01/t after midday on Nodal Exchange following the news, before sliding lower in later trade. Outside of the WCI, Washington is also likely to see a slowdown in its carbon market ambitions. The state Department of Ecology is conducting its own rulemaking to align Washington's "cap-and-invest" program to facilitate linkage with the larger WCI market. But it will require California and Quebec to finalize their expected changes. California has indicated over last year that it does not intend to focus fully on linkage until its current rulemaking is complete. California's and Quebec's cap-and-trade programs cover major sources of the state's GHG emissions, including power plants and transportation fuels.

Brazil's Bndes grants R480mn to ethanol producer

Sao Paulo, 14 January (Argus) — Brazil's Bndes development bank approved R480mn ($79mn) for sugar and ethanol producer CMAA to increase biofuel production in the state of Minas Gerais. The bank will grant R220mn from its Climate Fund to raise the private-sector company's anhydrous ethanol output in its Vale do Pontal sugar and ethanol unit, in Limeira do Oeste city, by around 1,470 b/d. The plant will be able to produce up to 3,650 b/d. With new investments, the Vale do Pontal plant will process 4mn metric tonnes (t) of sugarcane/crop, up from 2.7mn t/crop previously, producing hydrous ethanol, raw sugar and electric power for the Brazilian domestic market. The Climate Fund will be also used to double CMAA's power generation to 68MW. The remaining R260mn will be taken from Bndes' services and machinery program to modernize existing equipment and buy new agricultural machines. CMAA's Vale do Pontal, Vale do Tijuco and Canapolis units are expected to use R50mn, R160mn and R50mn, respectively. These resources can be allocated to buy, sell or produce machines, industrial systems or technological and automation goods, as well as hiring national services and machine imports, Bndes said. The company will also be able to increase issuance of Cbio carbon credits, following the rise in ethanol output.

EU air traffic growth threatens carbon budget: Study

EU air traffic growth threatens carbon budget: Study

London, 14 January (Argus) — European aviation's Paris climate agreement-aligned carbon budget will be depleted by 2026 if air traffic grows as industry expects in the coming years, according to a study by Brussels-based non-governmental organisation Transport & Environment. While the EU has pledged to reach net zero greenhouse gas emissions by 2050, the aviation sector is still expected to emit 79mn t CO2 by this date, according to scenarios put forward by European aircraft manufacturer Airbus and US-based Boeing. Airbus sees air traffic growing at an average rate of 5.7pc/yr in 2024-27 and by 2.6pc/yr in 2024-43, while Boeing expects a 5.6pc/yr rise in 2024-33 and a 2.5pc/yr rise in 2024-43, Transport & Environment said. If these projections are accurate, the aviation sector carbon budget needed to remain in line with the Paris accord's goal of limiting global warming to 1.5°C above pre-industrial levels would be depleted by 2026, the study found. Aircraft will have to burn 59pc more fuel in 2050 than in 2019 to meet this increased demand, the study found, even after taking into consideration efficiency improvements. This growth in traffic would also cancel out the benefits of sustainable aviation fuels (SAFs). The expected growth also implies that the sector could be burning as much fossil kerosine in 2050 as it did in 2023 — some 21.1mn t — even with 42pc of fuel use covered by SAFs under EU mandates, Transport & Environment said. The EU expects air traffic growth to be 60pc lower than the Airbus and Boeing projections. But even this smaller increase would mean emissions rising by 46pc by 2040 against 1990 levels, the study found. Transport & Environment called for all flights departing the EU to be included in the bloc's emissions trading system (ETS) by 2027, as part of efforts to make air ticket prices reflect the sector's climate impact. The scheme currently applies only to journeys within the European Economic Area. Tax exemptions on jet fuel should also be removed and value added tax applied to air tickets, the NGO said. It also recommended halting the expansion of airport infrastructure and improving rail infrastructure so that the railways can compete with air travel. And it called for penalties for non-compliance with SAF mandates and financial support for SAF production through auctions and contracts for difference. The European Commission's proposed target to cut the EU's overall net emissions by 90pc by 2040 from 1990 levels "is completely meaningless without concrete policies to reduce emissions from aviation", the NGO's aviation director, Jo Dardenne, said.
