Florida bans local net-zero policies
Gov. Ron DeSantis signed legislation on May 13 that restricts Florida local governments from adopting or enforcing net-zero policies aimed at cutting greenhouse-gas emissions. Creative Loafing Tampa Bay reported the law puts Tampa's 2023 Climate Action and Equity Plan in limbo while city legal staff reviews the implications. The move creates new uncertainty for local climate and resilience planning in a state facing heat, sea-level rise, and drought risks.
Why it matters
It directly narrows municipal climate authority in a major U.S. state.

Creative Loafing Tampa Bay coverageAnaergia wins first negative CI approval
Canada's Ministry of Environment and Climate Change granted Anaergia's Rhode Island Bioenergy Facility in Johnston, Rhode Island, a temporary negative Carbon Intensity score under the Clean Fuel Regulations. Global Renewable News reported the decision makes the U.S.-based renewable natural gas plant the first of its kind to receive a negative CI rating under the CFR, allowing it to generate credits. The facility captures landfill methane and processes more than 100,000 tons of organics a year into RNG, recycled water, and residuals.
Why it matters
It creates a new crediting pathway for U.S. RNG facilities selling into Canada.

Global Renewable News coverageAmazon signs multiyear heat pump deal
Amazon signed a multiyear agreement with Transaera for specially designed rooftop heat pumps for commercial buildings, Canary Media reported on May 13. The systems were tested in a six-month field trial at an Amazon logistics facility in Houston and are designed for all-electric heating and highly efficient cooling with built-in dehumidification. Amazon did not disclose unit counts, pricing, or installation sites, but linked the rollout to its 2040 net-zero target.
Why it matters
A major buyer is moving from pilot to procurement for higher-efficiency electrified HVAC.

Will temporary negative CI approvals scale?
Anaergia's ruling could become a template for other U.S. RNG plants seeking Canadian Clean Fuel Regulations credits.
