The committee's recent work has clustered around three broad files: the design and performance of climate and energy programs, the protection of water and nature, and the legislative and oversight business of the committee itself. On climate policy, witnesses have repeatedly returned to the question of whether federal programs deliver the emissions reductions they promise. A study of home energy retrofits heard that realized savings from the ecoENERGY program fell well short of model predictions, that the Green Municipal Fund's PACE-style financing has produced verified average household savings of about 30%, and that the building sector sees stable multi-year funding and third-party verification as essential. On industrial carbon pricing, witnesses split between those who described it as Canada's most effective remaining climate tool and those who said it is harming competitiveness and driving investment abroad, with several calling for harmonization across provincial systems and a credible post-2030 trajectory. Earlier meetings on plastics and on the Net-Zero Advisory Body surfaced similar tensions: industry witnesses argued the federal government has used the wrong instrument and caused economic harm, while environmental and academic witnesses defended existing bans and warned that policy rollbacks put net-zero out of reach.

A second cluster concerns water, flood and drought forecasting, and nature protection. Witnesses described Canada's forecasting capacity as fragmented across thirteen jurisdictions with no interoperability, and officials acknowledged that the National Hydrometric Program monitors water levels but does not issue warnings, which remain provincial. Debate over Bill C-241 turned on whether broadening the strategy's language to permissive "may take" measures strengthened or neutered the bill, and the committee ultimately adopted the government's amendment and reported the bill as amended. The Commissioner of the Environment and Sustainable Development's spring reports brought further scrutiny, with the audit finding slow production of flood hazard maps, eight years of missing public reporting on climate resilience, and weak documentation and an oversupply of avian influenza vaccine. Officials pushed back on several findings, defending the mapping program's pace and calling the flood portal a useful tool despite its address-search feature not yet being functional. On nature, the Secretary of State presented a $3.8-billion strategy while Parks Canada officials disclosed a $75-million budget cut and a maintenance deficit not covered by the new plan.

The committee has heard from a wide range of constituencies: academics and economists, environmental non-profits, industry associations representing plastics, cement, fertilizer and offshore oil, municipal representatives through the Federation of Canadian Municipalities, the Canada Green Building Council, and a large contingent of federal officials from Environment and Climate Change Canada, Transport Canada, the Coast Guard, Natural Resources Canada, Public Safety, Parks Canada, the Canada Water Agency, the Impact Assessment Agency and the Canadian Food Inspection Agency. Two witnesses who resigned from the Net-Zero Advisory Body testified that the body had become performative and was not consulted on major decisions. On Bill C-244, the Clean Coasts Act, officials broadly supported the intent while raising concerns about proving a buyer's ability and resources, the absence of definitions and prescribed forms, and the risk of inconsistent or discriminatory decision-making; the government's amendments added a strict liability clarification and replaced the transfer provision with a disclosure-and-confirmation requirement.

Several themes have persisted across the session. Witnesses who disagreed on policy usually agreed on the facts: that retrofit savings depend heavily on workmanship and verification, that program fragmentation raises costs, and that evaluation and measurement are weak. The most consistent disagreement was over instrument choice, with some witnesses urging performance-based outcomes and preserved consumer choice, including hybrid and high-efficiency gas systems, and others favouring heat pumps, fuel bans and production caps. Procedurally, the committee has spent noticeable time on motions and travel costs, including debate over COP travel expenses, a motion on the 2030 Emissions Reduction Plan, requests for an unredacted letter from Liberal MPs, and a defeated motion to keep the plastics study open. The most recent meetings have moved from witness testimony into clause-by-clause work on Bill C-244, with the committee adopting several amendments by voice vote and no recorded divisions.
