Scholars increasingly argue that entrepreneurs and their small-and medium-sized enterprises should play a central role in reducing the rate and magnitude of climate change. However, evidence suggests that while some entrepreneurs recognize their crucial role in addressing climate change, most do not. Why some entrepreneurs nevertheless concern themselves with climate change has largely been overlooked. Some initial work in this area tentatively suggests that these entrepreneurs may engage with climate change because of their personal values, which either focus on financial or socio-ecological reasons, or a combination of both. Yet, it is unclear if all for-profit entrepreneurs engage with climate change for the same reasons, or if indeed their motivations vary across business types. Over a period of four years, we examined entrepreneurs' motivations to engage with climate change through a variety of qualitative research methods. Our findings illustrate how entrepreneurs who address climate change have motivations specific to their business activity/ industry and level of maturity. In each instance, we link these motivations to distinct conceptualizations of time and place. We contend that, through a more differentiated understanding of entrepreneurial motivations, policy-makers can draft climate change-related policies tailored to entrepreneurial needs. Policies could both increase the number of entrepreneurs who already engage in climate change mitigation and leverage the impact of those entrepreneurs already mitigating climate change.

The construction industry is facing growing pressure to reduce carbon emissions. An important first step is to quantify emissions from construction projects enabling designs to be changed and emissions reduced. Whilst progress has been made in the development of carbon calculation tools, the uptake of these tools has been slow. This paper seeks to understand the reasons for the slow implementation of carbon calculation tools in the construction industry and provide guidance on how to overcome these challenges. We find there are specific issues that prevent tools being used such as data security and usability, but more general issues such as a lack of education or regulation also pose a challenge. Our findings suggest that despite the benefits that can come from using carbon calculation tools to reduce emissions, the use of tools on their own will be insufficient to achieve the needed carbon reduction and wider emissions-related change. Instead, carbon calculation tools need to be looked at within and across construction organisations through training, industry-wide standards and regulations as well as organisation-wide requirements and collaboration. The construction industry has a reputation for being slow to react to change, but if this industry waits for regulation before taking action, then the timescales involved may be too long given the pressing need to reduce emissions now. We recommend that for carbon calculation tools to be successfully integrated, the industry must work together to achieve more immediate change.

An often overlooked sector for achieving such a reduction in carbon emissions is the construction industry. Directly or indirectly, the construction and use of infrastructure assets accounts for over half of the United Kingdom's (UK's) total carbon emissions (Enzer, Manidaki, Radford, & Ellis, 2013) requiring reduction by 50% by 2025 (HM Government, 2013). Although growing attention has focused on how to reduce carbon emissions in this industry, only little change and reduction of emissions has been achieved so far (Xavier, Naveiro,

Carbon capture, utilization, and storage (CCUS) is a combination of technologies capable of achieving large-scale reductions in carbon dioxide emissions across a variety of industries. Its application to date has however been mostly limited to the power sector, despite emissions from other industrial sectors accounting for around 30% of global anthropogenic CO2 emissions. This paper explores the challenges of and requirements for implementing CCUS in non-power industrial sectors in general, and in the steel sector in particular, to identify drivers for the technology’s commercialization. To do so we first conducted a comprehensive literature review of business models of existing large-scale CCUS projects. We then collected primary qualitative data through a survey questionnaire and semi-structured interviews with global CCUS experts from industry, academia, government, and consultancies. Our results reveal that the revenue model is the most critical element to building successful CCUS business models, around which the following elements are structured: funding sources, capital & ownership structure, and risk management/allocation. One promising mechanism to subsidize the additional costs associated with the introduction of CCUS to industry is the creation of a ‘low-carbon product market’, while the creation of clear risk-allocation systems along the full CCUS chain is particularly highlighted. The application of CCUS as an enabling emission reduction technology is further shown to be a factor of consumer and shareholder pressures, pressing environmental standards, ethical resourcing, resource efficiency, and first-mover advantages in an emerging market. This paper addresses the knowledge gap which exists in identifying viable CCUS business models in the industrial sector which, with the exception of a few industry reports, remains poorly explored in the academic literature.
