What can Rotterdam do to fight global warming? What is the city’s current CO2 budget? How can it become carbon-neutral in the run-up to the 2050 Paris Agreement deadline?
Rotterdam is looking to accelerate its transition to becoming an emission-free city, as it seeks to become a more sustainable and inclusive place to live. The transition towards a green economy includes tackling energy and mobility poverty among city residents and becoming more resilient.
Together with DRIFT, the sustainability research institute at Rotterdam’s Erasmus University, Arup provided an overview of the challenges and opportunities that the city – which hosts Europe’s largest port – faces as it transitions to become carbon neutral by 2050. The New Energy for Rotterdam report, the result of the Pathways to Paris project, addresses some of the pressing issues facing cities going green.
2.7 megatonnes of CO2 is Rotterdam’s annual baseline
4.44tonsof annual emmision per inhabitant
Net Zero to be achieved by 2050
This report can be a leading example for the Netherlands and other C40-cities of how the Paris Agreement on climate change. The researchers advise to form coalitions with big and small parties on several topics in order to scale up the initiatives, while involving and engaging citizens and organisations in the transitions. ” Adriaan Visser Alderman Finance, Organisation, Port, Sports, Mobility and Sustainability, City of Rotterdam
Towards a carbon-neutral city
As a technical partner, Arup worked with the city to understand the carbon impact of its activities and products, analysing Rotterdam’s baseline carbon consumption and modelling two likely of CO2 scenarios as it seeks to become carbon-neutral:
1. A market-oriented pathway, which focuses on all-electric solutions. Assuming that Rotterdam will deliver 73,000 new buildings and renovate no less than 213,000 homes over the next 30 years; this scenario focuses on how individuals can commit to very low temperature buildings, use to sustainable individual transport and rely on heat pumps for heating. In the area of mobility, individual transport is stimulated and half of the transport within the city would take place with an electric vehicle.
2. The collective pathway, which mainly focuses on collective solutions like a low-temperature heat network, the use of geothermal energy and other renewable sources, as well as the use of collective sustainable transport. This scenario assumes that 243,000 homes will be renovated in the next 30 years, with 15,000 demolished and a further 43,000 newly built. In terms of mobility, individual car use would be drastically reduced with most city-dwellers travelling by foot, cycling and other forms of micro mobility; and an increase in the use of public transport.
The current challenges for Rotterdam
As Europe’s largest port and a leading industrial centre, Rotterdam has relatively high annual carbon emission levels. According to the research, the city can emit another 36 megatons of CO2 until 2050, but is likely to exceed its carbon budget by 2030 if no measures are implemented. In the short term, the report identifies two key actions: making the urban area within the city ring emission-free within five years, and phasing out the use of natural gas for heating by 2035, a measure which would require upgrades to the electricity grid and heating networks.
Rotterdam is committed to finding future-proof solutions to reduce its carbon footprint and become carbon-neutral by 2050. However, the city will not be able to achieve its climate action pledge alone: input from the government, province, industries such as the port, as well as changes in city residents’ behaviour will also be necessary.
The report is the first calculated roadmap for a carbon neutral city in the Netherlands. The two pathways charted by Arup form the basis for the Municipality Coalition Agreements, and are an inspiring example for other cities to reach their climate goals. Arup also works with the C40 Cities Climate Leadership Group (C40), of which Rotterdam holds membership.
