CCAC projects rise in industrial greenhouse gas emissions

Ireland’s industrial greenhouse gas emissions have fallen for four consecutive years. However, the Climate Change Advisory Council projects that this progress will stall and emissions will rise again toward the end of the decade. This matters because industry is expected to become Ireland’s second worst-performing sector after transport against its climate targets.

The projected 2030 reduction is only 11.6% compared with 2018 emissions. That is much smaller than the Government’s target of a 35% reduction. Industrial emissions fell 3.3% last year, reaching six million tonnes of CO2 equivalent, but the council warns that recent progress cannot be taken for granted.

The council says planned Government measures are insufficient. It also highlights barriers to electrification, biomethane production, grid connections, and low-carbon technologies. Unless these barriers are removed and stronger policies are introduced, industrial emissions are expected to increase again rather than continue falling toward 2030.

Industrial greenhouse gas emissions are climate-warming gases released by industrial activity. They include emissions from manufacturing and industrial heating, where fossil fuels may be burned to produce heat or power. They can also come directly from processes such as making cement and lime. Waste-related emissions are discussed alongside industry in the council’s sector review.

The article identifies several activities linked to these emissions. Industry uses fossil fuels in heating and manufacturing processes. Cement and lime production may require lower-carbon technologies, carbon capture, transport and storage. Waste management also matters because Ireland generates large quantities of waste and exports much of its municipal waste for final treatment.

These emissions matter because they contribute to Ireland’s national total and must fall to meet climate targets. Industrial emissions currently represent 11.4% of national emissions. Reducing them will require cleaner electricity, more biomethane, approved low-carbon cement and concrete technologies, and better waste reduction and recycling.

Ireland’s Government has set a target of reducing industrial emissions by 35% from 2018 levels by 2030. The Climate Change Advisory Council says current projections point to only an 11.6% reduction. The difference is therefore 23.4 percentage points, a substantial gap for the sector to close within the decade.

For example, if 2018 emissions are treated as 100 units, the target would bring them down to 65 units. The projection would bring them only to 88.4 units. That leaves emissions 23.4 units higher than the target pathway. The comparison shows why the council says current measures are not sufficient.

The gap also reveals a policy problem. EPA projections show almost no difference between reductions from existing measures and reductions after the additional measures listed in the Climate Action Plan. The council says this indicates a lack of clear policies capable of delivering the missing reductions.

Industrial emissions are expected to rise again because the measures currently planned do not appear strong enough to deliver the reductions required by 2030. The council says EPA projections show almost no difference between the effect of existing measures and the effect of additional measures listed in the Climate Action Plan.

Several practical barriers are slowing the transition away from fossil fuels. Companies face difficulties electrifying industrial processes, high costs and delays for electricity grid connections, inadequate support for biomethane production, and lengthy approvals for lower-carbon technologies. Low-carbon cement and concrete proposals have sometimes waited years for decisions.

The result is that recent falls may not continue. Industrial emissions declined 3.3% last year, but the council warns that this progress cannot be assumed to continue. It wants stronger policies, faster approvals, better biomethane supports, cheaper grid connections, and a framework for commercial carbon capture, transport and storage.

A carbon budget sets a permitted ceiling for emissions over a defined period. Exceeding it means the sector has emitted more greenhouse gases than allowed for that budget period. The article does not state what legal or financial consequence follows for Ireland’s industrial sector, so no specific penalty can be identified from the text.

Industry has provisionally exceeded its ceiling for the first carbon budget period, covering 2021 to 2025. The overrun is 2.7 million tonnes of greenhouse gases, equal to 9.1%. This is an early warning that the sector’s emissions pathway is already above the permitted limit.

The article does not give one precise reason for the overshoot. It links the wider problem to insufficient planned measures and barriers to cleaner production. These include difficult electrification, weak biomethane investment, grid delays, and slow approvals for low-carbon technologies. The council says stronger action is needed to prevent further shortfalls.

Industry could lower emissions by replacing fossil fuels with renewable electricity and domestically produced biomethane. Low-carbon cement and concrete could reduce emissions from construction materials. Carbon capture, transport and storage could also help cement and lime production. These alternatives matter because industrial heating and manufacturing currently depend partly on fossil fuels.

The article gives several examples of the barriers. Electrifying processes is difficult, while grid connections involve costs and delays. Biomethane development is held back by piecemeal implementation of the National Biomethane Strategy and an unattractive investment case. Only seven projects received first-round grant approval. Low-carbon cement and concrete proposals have also faced years-long approval delays.

The council wants faster grid connections, a Renewable Heat Obligation, and separate biomethane financial support. It also wants quicker technology approvals and a legal framework for commercial carbon capture, transport and storage. These changes are intended to turn available alternatives into operating industrial solutions.

A carbon budget is a fixed ceiling for greenhouse gas emissions over a defined period. It translates a country’s long-term climate ambition into a measurable limit for particular years. Ireland’s first five-year carbon budget period runs from 2021 to 2025, and industry has a permitted share within that overall system.

The mechanism is cumulative. Emissions released in one year use part of the available budget, leaving less room for later years. If a sector exceeds its ceiling, its actual emissions are above the pathway planned for climate action. Ireland’s industry has provisionally exceeded its first permitted ceiling by 2.7 million tonnes, or 9.1%.

Carbon budgets connect sector decisions with the larger climate goal because national emissions must stay within agreed limits. The article does not describe the specific penalty for exceeding a budget. It does show that overshooting makes future reductions more difficult and strengthens the case for faster action.
